Abstract
A high density construction board includes a cellular body having a first planar surface and a second planar surface. A first glass facer is positioned adjacent the first planar surface and a second glass facer is positioned adjacent the second planar surface. The cellular body of the construction board includes a polyurethane, a polyisocyanurate, or a mix of polyurethane and polyisocyanurate and has a density greater than about 2.5 pounds per cubic foot and less than 6 pounds per cubic foot.
Claims28
A high density construction board comprising:
- a cellular body having a first planar surface and a second planar surface,
- a first facer adjacent said first planar surface and a second facer adjacent said second planar surface,
- wherein said cellular body includes a polyurethane, a polyisocyanurate, or a mix of polyurethane and polyisocyanurate and has a density greater than about 2.5 pounds per cubic foot and less than 6 pounds per cubic foot, and wherein said first facer and said second facer are formed from materials selected from the group consisting of coated glass fiber mats, uncoated glass fiber mats, chopped glass, and combinations thereof.
A covered roof comprising:
- a roof deck;
- and
- a high density construction board comprising a cellular body having a first planar surface and a second planar surface, a first facer adjacent said first planar surface and a second facer adjacent said second planar surface, wherein said cellular body includes a polyurethane, a polyisocyanurate, or a mix of polyurethane and polyisocyanurate and has a density greater than about 2.5 pounds per cubic foot and less than 6 pounds per cubic foot, and wherein said first facer and said second facer are formed from materials selected from the group consisting of coated glass fiber mats, uncoated glass fiber mats, chopped glass, and combinations thereof.
A method of covering a roof comprising:
- applying a high density construction board to the roof, the high density construction board comprising a cellular body having a first planar surface and a second planar surface, a first facer adjacent said first planar surface and a second facer adjacent said second planar surface, wherein said cellular body includes a polyurethane, a polyisocyanurate, or a mix of polyurethane and polyisocyanurate and has a density greater than about 2.5 pounds per cubic foot and less than 6 pounds per cubic foot, and wherein said first facer and said second facer are formed from materials selected from the group consisting of coated glass fiber mats, uncoated glass fiber mats, chopped glass, and combinations thereof.
